libcrypt on ARM5

I'm trying to compile libcrypt on a SheevaPlug running Debian Squeeze, but it keeps giving me the following error:

invalid operands to binary != (have ‘va_list’ and ‘void *’)

is there any way to get this thing to compile without major hacking?

ARM5
Surely you mean ARMv5... right?

It sounds like you've already had your hands all over it. Try casting a spell.
